Construction, Modeling and Control of a Metal Forming Machine

Research output: ThesisMaster's Thesis


In this thesis, the assembly and control of a device for forming sheet metal is presented. Based on a CAD design already completed in a previous project, the mechanical components were assembled and properly aligned. After the functional design was checked, the system was electrified by laying out its own control cabinet with drive components and wiring the machine accordingly. The motors, three in number, drive two axes to achieve independent movements in the horizontal and vertical directions. On the one hand, a parallel, rigid coupling, a so-called gantry axis, as well as an axis coupling of this axis group and another axis for path-controlled movements was implemented in the control. While axis control was only made possible by the development of models for the mathematical description of the machine kinematics and kinetics, the cascade control that is standard on the axis drives used is to be improved by a model of the machine dynamics. With the help of a human-machine interface, machine operation was ultimately simplified in such a way that end users can also carry out test series for recording technology data. A final proof of function checks compliance with the specified requirements. Due to its rigid design, this device supports the determination of machine-independent forming technology data. The knowledge gained from semi-analytical simulations and FEM models is to be supported and verified. The improvement of the data basis and the data models on which the machines are based contribute significantly to the optimization of the bending results while at the same time shortening the running-in times.
